CABURETOR HEATER FOR AUTOIOBILES Filed Aug. 12, 1929 Patented Aug. 26,1930 UNITED STATES PATENT OFFICE RAGNAR O. HEGGELUND AND HELMER I.SETBAGKEN, OF LAKE PRESTON, SOUTH DAKOTA CARBURETOR HEATER FORAUTOMOBILES Application filed August 12, 1929. Serial No. 385,116.

This invention relates to improvements in carburetor heaters forautomobiles or for gasolene engines used in conjunction with a storagebattery. One object is to provide a carburetor heater that can beapplied eX- teriorly to the shell of the carburetor readily and withoutalteration of the same and as readily removed if desired. A furtherobject is to provide a carburetor heater of few parts,

simple in construction and that can be adjusted to deliver more or lessheat as may be desired.

With the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed, pointed out in the claims and illustrated in the accompanyingdrawing which forms a part of this application for patent and in which-Fig. 1 is a view of a carburetor illustrating the application of theheater.

Fig. 2 is an enlarged fragment-ary sectional view of Fig. 1.

Fig. 3 is a fragmentary side view of Fig. 2.

Fig. 4 is a top plan view of the heater element with the cover removed.

Like reference characters denote corresponding parts throughout theseveral views.

The carburetor heater comprises a vessel having a body portion ofinsulation material and a cover of good heat-conducting material, thecover being placed against the base of the carburetor to heat thegasolene therein suiiciently to cause it to vaporize readily. Thisvessel is adjustably secured to the carburetor shell by angular armsclamped to its sides and to the top of the shell.

The reference numeral 1 denotes a conventional type of carburetor. Theheater comprises a vessel having the body or container portion 2 made ofinsulation material and provided with the close fitting removable cover3 of a heat conducting material, the base of said portion 2 beingperforated to receive the binding posts 4, 5 to which the resistancecoils 6. 7, 8 are secured, said posts having secured thereto also theleads 9, 10 that run to the storage battery (not shown).

The cover 3 is preferably of a size and shape to fit closely against thebottom of the carburetor so that the heat generated in the i vessel maybe passed readily to the carburetor to heat the contents thereof. Acollar 11 is formed with a flange 12 to receive and support the vesselbody 2, said collar being of a diameter and size to permit itsengagement with the cover 3 and the shell of the carburetor. A pair ofangular arms 13, 14, each of which is formed with an elongated slot 15,are adapted to be secured by screws 16 to the collar 11, the upper bentends of said arms engaging with the top of the carburetor whereby tosecure the heater to the carburetor. An adjustment of the collar andheater relative to the carburetor shell is possible by slightlyloosening the screws 16 and after the desired adjustment is effected,tightening the screws again.

What is claimed is l. In a carburetor heater, a vessel comprising a bodyportion of insulation material and a top of heat conducting material forapplication to the base of the carburetor, resistance coils within saidvessel, a supporting collar for said vessel, and clamping means forsecuring said collar to said vessel and the carburetor shell.

2. In a carburetor heater, a vessel comprising a body portion ofinsulation material and a top of heat conducting material forapplication to the base of the carburetor, resistance coils within saidvessel, a supporting collar releasably connecting said vessel and thecarburetor shell, angular longitudinally slotted arms for application tosaid collar and carburetor shell, and screws for connecting the slottedportions of said arm and said collar.

3. In a carburetor heater, a vessel for application to the base of thecarburetor. resistance coils within said vessel, a supporting collar forsaid vessel, and clamping means for securing said collar to said vesseland to the carburetor shell.

4. In a carburetor heater, a vessel comprising a. body portion ofinsulation material and a top of heat conducting material for closeitting engagement with the base of the carburetor shell, resistancecoils within said body portion, a flanged collar releasably engagng thecomponent members of said vessel and the carburetor shell, angular armsfor connecting said collar and carburetor shell, and screws connectingsaid arms and Collar.

In testimony that We claim the foregoing as our own We have hereto a'xedour Sgnatures.
